The ''charge stored'' by a capacitor refers to the magnitude of the charge stored on each plate in a parallel plate capacitor or on the surface of a spherical conductor. The capacitor itself does not store charge. The letter ''C'' is used both as the symbol for capacitance as well as the unit of charge (coulombs).

• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The is equal to the electrostatic pressure on a surface.
These are the plates of a cylindrical capacitor. We give the inner plate a charge Q and the outer plate a charge −Q. The charge per unit length on the inner plate is λ = Q/l and on the outer plate is −λ = −Q/l.
Figure 5.10.4 Spherical capacitor filled with dielectrics. The system can be treated as two capacitors connected in series, since the total potential difference across the capacitors is the sum of potential differences across individual capacitors. The equivalent capacitance for a spherical capacitor of inner radius 1r and outer radius r
Say you have an isolated capacitor with charge Q. Initially, the capacitor is embedded in vacuum (or air which is nearly vacuum for dielectric properties) and has potential V0. The capacitance is V0 Since the capacitor is isolated the charge cannot change. Now magically you embed the capacitor in a uniform dielectric with dielectric constant κ.
If the potential difference gets too large (which implies a large electric field), charge will start to flow between the plates. It can be pulled off the surface of the plates if the capacitor has vacuum between the plates and if there is a dielectric between the plates (which is usual), then the dielectric can break down (i.e., start to conduct).
The left plates of both capacitors C1 and C2 are connected to the positive terminal of the battery and have the same electric potential as the positive terminal. Similarly, both right plates are negatively charged and have the same potential as the negative terminal. Thus, the potential difference | ∆ V | is the same across each capacitor.
